It’s fair to say most people will exaggerate on their CV in the hope of landing a dream job.

Some might bump up their grades a notch or two, while others will try and appear a bit more cultured by dropping in a fake interest in opera or classical music.

So when former supermarket shelf stacker Kevin Watson, 42, applied for a job as Deputy Head Groundsman at Saracens Rugby Club, he thought nothing of planting a few porkies among his key skills.

He dreamed up former roles as a trainee groundsman at some of sport’s biggest venues, including London’s Wembley Stadium, Barcelona’s Nou Camp and Lord’s cricket ground - and his lies did the trick, landing him the job.

But what he didn’t count on was that his so-called services would be called upon as early as his first day before he could learn the ropes. And that he would be making his debut with the pitch marker in front of an army of TV cameras.

Kev’s boss and Head Groundsman John Maguire had been due to do the honours but when his car broke down he ordered new boy Kev to step in to capture the footage...with hilarious results.

Puzzled TV crews looked on as he completely dropped the ball in his attempt before trying to cover up his gaffe by blaming the machinery.

The Mirror has obtained the clip which captured Kev's attempt to paint the pitch, which sees him blatantly guessing his way around the turf planting wonky lines all over the place in bright white paint.

After finishing the shoot, TV crews packed up their gear and left but when Kev's boss John arrived he was shocked to find the pitch had been ruined and demanded answers, forcing the new boy to come clean. He was then sacked on the spot.

Kev said: “Looking back at it now, it was quite funny - but I can assure you it wasn’t at the time. I knew enough about rugby to land the job and my CV obviously impressed the team but I’ve got no clue where the lines are meant to go or how long they’re supposed to be so I just had to guess!

“I’m sure people will have a laugh watching the video of me making a right hash of it. I’ve already had loads of people messaging me to take the mickey.”

Kev’s handiwork had to be washed away using high-powered hoses before Head Groundsman John could re-do the job and invite the cameras back in. An insider added: “It’s just lucky there wasn’t a game due to take place the next day - those lines really would have confused the players.”

Ok, this isn’t real - but we could imagine a rugby star giving this tough task a try. Whether it’s accurately painting a pitch or attempting to calculate an energy bill, if you’re relying on an estimate you won’t get an accurate result.

With a smart meter you won’t have to rely on estimated bills any more or have to phone in your meter reading.

Every home in Britain will be able to get a smart meter by 2020 at no extra cost. You will be able to monitor your gas and electricity use in pounds and pence in near real-time, and bring an end to estimated energy bills.

Smart Energy GB is the national campaign for Britain’s smart meter rollout.
